Add a VM and specify the ServerName.

By default, there is an advertisement on the host.

ServerName server name. It is used to create URL redirection. ServerName is one of the tags used by the apache server to identify access requests. it does not have to be the same as the actual IP address or DNS name. You can also leave this parameter unspecified. in this case, apache tries to use an IP address as the request flag. You can also leave the port unspecified.
Example: ServerName www.example.com: 80

Change the httpd. conf file
------ Solution --------------------
Httpd can be modified. conf file. you may need to use php or js to load most files on your website. for example, add
If ($ _ SERVER ['server _ name']! = 'Your website domain name ')
{
Echo "cannot access me like this"; // do something
Exit;
}
?>
------ Solution --------------------
Rewrite the domain name to overwrite other domain names that are not your own domain name to your domain name.

ServerName *******
DocumentRoot/advertisement/
